基坑工程开挖的最终状态与开挖过程密切相关，用施工时变力学的方法对基坑施工过程对周围环境的影响进行预测分析，可以优化施工方法，并与施工实测数据进行比较，保证结构施工的安全进行。本文以某实际基坑工程为研究对象，利用ABAQUS有限元分析软件建立基坑开挖的三维有限元分析模型，模拟该基坑工程开挖过程，对基坑开挖进行全过程模拟，分析了基坑开挖对周边场地的影响。本文主要考虑了基坑开挖过程中施工步骤、分层开挖深度、周边建筑的位置、层数、数量等因素对基坑周围环境的影响，并得到一些有益结论，为基坑工程的设计和施工提供了一定的数值参考依据。

The final state of excavation engineering is closely related with the excavation process. The construction time-varyingmechanicalmethod is used to predict the effect of excavation process on the surroundings. The analysis can be used to select and guide the construction of excavation engineering. And it can be used to real-time analysis by comparing with themonitoring data to ensure the construction safety. A three-dimensional finite element analysismodel of excavation engineering and the surroundings is established by using of ABAQUS. The construction process is simulated in this paper. The effect on surroundings during the construction process of excavation engineering is studied. The influence parameters, such as construction procedure, each excavation depth,meanwhile, the location, layers, and number of the surrounding buildings are considered. Some value conclusions are drawn. The study provides certain reference value for the design and construction of excavation engineering.
